Software Engineering @ SSL● We believe in practicality and simplicity - bringing order and clarity in
complexity
● Our approach to software engineering is based on these two key pilars
● Exerting the right amount of engineering delivers solutions which are cost effective and helps to meet the KPIs of customer requirements
● We don't strive for perfection
● IT landscape is highly volatile and disruptive - like no other domain
● Replenishment cycles of IT are very short and constant
● Designing for the future is not practical and prudent nor is it thrifty in the long run
● Refer to SSL publication http://www.slideshare.net/SoftwareServicesLanka/15bd22ce-120041d98684756928788a53sslse
● We believe in open source and standards based technologies
● Its pragmatic - proven, widely used, productive, cost effective and pertinant
● Specially in the current climate with almost everyone grappling with economic challenges

Software Engineering @ SSL ● We believe in the potential of the cloud platform as viable cost effective
alternative for on demand infrastructure for application deployment, support and maintenance – pay as you go – from CAPEX to OPEX Model
● Software usability is key for user acceptance of software and adoption
● Lack of software usability is the key cause for software adoption faliures
● Get users involved in the user interface designs of the software early so that they know what they are going to live with
● Refer SSL publication http://www.slideshare.net/SoftwareServicesLanka/6968a4de-da64425a8d31a898600f1701sslsu
● We believe for the forseable future the internet to be the platform for software
● Acess and reach – web browser based user interfaces
● Central deployment and integration
● Management, maintenance and support● Refer to SSL publication

Software Engineering @ SSL ● REQUIREMENTS : Requirements are critical to the success of any engineering
undertaking.
● Misses or misinterpretations can lead to frustration, misunderstanding and costs.
Garbage In > Garbage Out (GIGO).
● The Requirement Clarification Document (RCD) enables SSL to capture, articulate and discuss the requirements of the customer with clarity. The RCD is UI, Interface and requirements driven and helps to minimize misses and misinterpretations.
● Once the RCD is approved by the customer, it functions as the key input for the Proposal for Software Engineering (PSE) [Scope + Functionality + Estimation + Schedule + Price], Design and Testing.

Software Engineering @ SSL ● DESIGN : Approval of the RCD initiates the design process at SSL.
● The scope of PSE is per the approved RCD.
● Any subsequent requirements that are beyond the RCD will be treated as Change Requests for Software Engineering (CRSE) and will specified, priced and scheduled accordingly.
● The PSE comprises of (Scope, Price, Schedule and Terms & Conditions).
● Approval of the PSE will initiate the design work
● Key UIs are identified and conceptual designs are provided for customer approval.
